He. La Cells https: //www. youtube. com/watch? v=y 38 pg. PY 6 Zq 0 A He. La cell (also Hela or hela cell) is a cell type in an immortal cell line used in scientific research. It is the oldest and most commonly used human cell line. The line was derived from cervical cancer cells taken from Henrietta Lacks, a patient who eventually died of her cancer on October 4, 1951.

Rules of Debate Timer set for 30 minutes Counts as a quiz grade! Review rubric!
Debate Reflection For homework tonight, I want you to write a reflection paper of our debate. Your responses must be thoughtful and reflective IB Traits: REFLECTIVE, COMMUNICATOR
4 types of tissues 1. epithelial tissue 2. connective tissue 3. muscle tissue 4. nervous tissue
Epithelial tissue includes… 1. layers of cells that cover internal or external surfaces 2. glands
Some important characteristics are… 1. cells are close together 2. a free surface exposed to environment or internal chamber/passageway. 3. attachment to basement membrane � provides barrier 4. no blood vessels (avascular) 5. continually replaced and regenerated
Functions of epithelia… 1. Provide physical protection 2. Control permeability � What comes in and out 3. provide sensation 4. produce specialized secretions � Exocrine= secretions released to surface of skin � Endocrine= secretions released as hormones into tissue fluid & blood
Warm – up 8/20 -21/2015 Essentials: Epithelial Chart, Cheek cell lab, exit ticket slip Warm-Up: - - - Turn in your reflective essay (staple to rubric) Label the tissue types (Tissues IP) Agenda v DOL: Scholars will be able to identify epithelial and tissue types by cell structures. v Lab: Cheek cells and epithelial layers v v Homework: Tissue Poster Reading Chap. 5, Connective tissue IP Announcements: - Quiz Monday Connective Tissue IP due Monday Tissue Posters (DUE WEDNESDAY) Test August 28 th / Review on Wednesday
Epithelial cells are classified by amount of layers and shape… LAYERS Simple = one layer stratified = multiple layers Pseudostratified = looks like multiple layers SHAPE Squamous = thin/flat Cuboidal = shaped like a cube or hexagon (6) Columnar = long and skinny Ciliated = contain cilia
An example… One layer with tall and skinny cells � Simple columnar Multi-layered and square shaped � Stratified cuboidal
Pseudostratified Ciliated Columnar Location: respiratory tract (nasal cavity, larynx, trachea, bronchi) Function: cilia moves mucus across the surface of the cells, protection
Glands Endocrine glands – secrete hormones directly into the bloodstream � Hormones are chemical messengers that influence cells in the rest of the body Exocrine glands – use different processes to release secretions � Ex: sweat glands, mammary glands, salivary glands
The purposes of Connective Tissue… Bind (hold things together) Support & protect Fill spaces Store fat Produce blood cells
Locations: �Widely distributed throughout the body Facts: �Good blood supply �Farther apart than epithelial cells �Connected with matrix
Exit Tickets 1. a single layer of cells that are thin and flat are called: 2. a multi-layered group of cells that are long and skinny are: 3. a single layer of square cells 4. What connective tissue is responsible for storage of energy? SHOUT OUTS!
Warm – up 8/20 -21/2015 Essentials: Types of epithelial tissue, sheet of legal paper, quiz sheet, Tissue review packet (1 per table) CLASS SET! Warm-Up: - - - At your table review types of tissues and their function. 5 minutes QUIZ TODAY! Agenda v DOL: Scholars will be able identify tissue types and relate its structure to function by location. v Homework: Tissues posters (quiz grade) Announcements: - Test August 28 th Test review Wednesday come prepared!
Classification of Connective Tissue 1. Connective tissue proper Loose connective tissue a. i. iii. b. Areolar Adipose Reticular Dense connective tissue Supporting connective tissue 2. a. b. Cartilage Bone Fluid connective tissue 3. a. Blood
1. a. Loose Connective Tissue lies under skin, connect it to organs, provides blood supply The body’s “packing material”
1. a. i. Areolar Function: Protects tissues and organs, binds epithelia to deeper tissue Location: dermis (skin)
1. a. ii. Adipose Function: stores energy, insulates & cushions Location: subcutaneous layer (deep to skin), surrounding organs
1. a. iii. Reticular Function: provides support to lymphatic system organs Location: spleen, lymph nodes, thymus, bone marrow
1. b. Dense Connective Tissue very STRONG, used to bind parts together Function: attaches bone to bone (ligaments), muscle to bone (tendon) Location: ligaments, tendons
1. b. Dense Connective Tissue Ligaments �Connects BONE to BONE Tendons �Connect MUSCLES to bone
2. a. Cartilage Function: Protects, absorbs shock (in joints) Location: tip of nose, ends of long bones, intervertebral discs, external ear
2. b. Bone very rigid, heals quicker than cartilage Function: provides support (more than cartilage) and levers for movement Location: bones of the body
3. a. Blood Function: helps transport and maintain internal environment Location: blood vessels, heart
Tissue Rotations and Cheek cell Lab
Station Expectations One group at each station 2 min at each station Rotate clockwise
Tissue Posters Four types of tissue Location of tissue Purpose/function of each tissue Classification of tissue Memory Device (How you will remember each type) Drawing of each type of tissue Creativity/color Neatness This will count as a quiz grade!
